Description
The M25P10-A is a 1 Mbit (128 Kbit x 8) serial Flash memory, with advanced write
protection mechanisms, accessed by a high speed SPI-compatible bus.
The memory can be programmed 1 to 256 bytes at a time, using the Page Program
instruction.
The memory is organized as 4 sectors, each containing 128 pages. Each page is 256 bytes
wide. Thus, the whole memory can be viewed as consisting of 512 pages, or 131,072 bytes.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time,
using the Sector Erase instruction.
